Question

The primary features of differentiation between ruminants and non-ruminants are the presence of which of the structure in ruminants?

• A. 5 chambered stomach
• B. 4 chambered stomach
• C. 3 chambered stomach
• D. 1 chambered stomach

Answer 1

Answer: (B)

4 chambered stomach

Ruminants have 4-chambered stomach. The four chambers are namely rumen, reticulum, omasum and abomasum. Like other vertebrates, ruminants (including deer and cattle), are unable to digest plant material directly, because they have 4-chambered stomach for better digestion.

So the correct answer is '4-chambered stomach'.
